This is surprisingly fun for something so simple. I like how some of the items are new attacks and some are like modifiers for them, that's pretty unique. Still don't know what the hammer does though or how exactly the order changes things. Using the number keys for picking up the items is extremely awkward. It would be nice to have more enemy variation and more items. The little fireball seems just straight up worse than the big line. It's very hard to pick up a new item when you're not strong enough to get the ghosts out of the way (specially with the awkward keybinds), and that's exactly when you need to get new items. You get very strong very fast past that. Oh and it's quite laggy, specially when shooting.
